What is Flowrite?
Flowrite is an AI-powered email and message assistant that transforms brief instructions or bullet points into polished, ready-to-send emails. Designed for professionals, sales teams, and everyday users, it helps you save time, overcome writer's block, choose the right tone, and maintain professional communication across all your email interactions.
How Flowrite Works
Simply provide a short prompt—such as "Follow-up with client about meeting next week" or "Thank you email to job interviewer"—and Flowrite's AI generates a complete draft email. The system intelligently considers context, tone (formal, friendly, persuasive), and writing style to create appropriate messages.
With seamless integration into Gmail and Outlook, you can trigger the assistant directly within your email client and insert generated text via the browser extension. Following the 2024 acquisition by Maestro Labs, Flowrite's technology has evolved into the MailMaestro platform, expanding beyond basic email drafting to include advanced productivity features.
Key Features
Convert bullet points or brief instructions into complete, professional email drafts in seconds.
Choose from multiple writing tones—formal, casual, friendly, persuasive—to match your recipient and context perfectly.
Access a comprehensive library of email templates for common scenarios: introductions, outreach, reminders, and follow-ups.
Works directly within Gmail and Outlook through browser extension for uninterrupted workflow.
Draft emails in various languages with appropriate tone adaptation for global communication.
Paste existing text and let AI polish, rewrite, or improve your drafts for better clarity and impact.
Create personalized keyboard shortcuts and let the tool learn your writing style over time.
MailMaestro evolution includes inbox triage, thread summarization, and advanced email management features.
Download or Access Link
How to Use Flowrite

Click generate to create your email draft. Review the output carefully and edit any specific details like names, dates, or attachments as needed.
When satisfied with the draft, copy or insert it directly into your email client and send your message.
Set up custom shortcuts and templates for recurring phrases to accelerate future email writing. If using the MailMaestro-powered version, explore inbox triage and thread summarization features for enhanced productivity.
Important Limitations & Considerations

- Free versions impose limits on message volume and available features; full functionality requires a paid subscription
- Generic or vague prompts may produce less relevant or overly generic email drafts
- Browser extension compatibility may vary by email client, browser version, or corporate security policies
- Some corporate environments restrict browser add-ons—check with your IT department before installation
- Quality of AI-generated text depends directly on the clarity and detail of your input prompt
Frequently Asked Questions

Whether you're drafting professional emails, refining messages, or brainstorming ideas, GrammarlyGO reduces writing effort while improving communication quality.
How GrammarlyGO Transforms Your Writing
If you regularly write emails, reports, or documents, you've likely experienced writer's block, tone mismatches, or excessive time spent on wording adjustments.

The tool integrates seamlessly into your existing workflow—Gmail, Google Docs, Microsoft Word, or any browser-based writing space—so you can maintain focus without switching applications. Beyond error correction, GrammarlyGO offers tone adjustments, text rewriting, idea generation, and smart features like email thread summarization and context analysis.

Download the browser extension (Chrome, Firefox, Edge, Safari), desktop app (Windows/macOS), or mobile app (iOS/Android) based on your preferred platform.
Within the Grammarly editor or browser writing spaces (Gmail, Google Docs), look for the "GrammarlyGO" or lightbulb icon to access generative AI features.
Decide whether to compose new text, rewrite existing content, reply to an email, or brainstorm ideas. Provide a clear instruction prompt (e.g., "Write a friendly email asking for a project update") or highlight text for rewriting.
Select your desired tone (formal, casual, direct), length, or style to ensure the output matches your communication intent and brand voice.
Carefully review the generated draft. Adjust names, dates, attachments, or other specifics. Refine the text as needed, then insert or copy it into your email or document.

Important Limitations

- Prompt Quality Matters: Clear, specific prompts yield better results. Vague instructions may produce less accurate or relevant output.
- Specialized Writing: For heavily technical, legal, or scientific content, additional domain-specific review is necessary beyond AI suggestions.

維持專業標準
清晰的主旨欄
主旨欄要具體且相關。簡潔的主旨讓收件人知道預期內容，避免電郵被忽略。
- 好例子： 「項目更新：4月15日會議」
- 差例子： 「更新」
禮貌且專業的語氣
始終保持正式和禮貌。AI工具有幫助，但你應核實語氣是否合適。
- 避免在工作電郵中使用俚語、表情符號或笑話
- 使用積極且尊重的語言
- 選擇合適的稱呼（如「尊敬的Smith博士」或「團隊您好」）
簡潔結構
保持電郵重點突出且易於瀏覽。人們常常快速瀏覽，清晰和簡潔至關重要。
- 將正文分成短段落或項目符號
- 先說明目的，再提供詳情
- 突出關鍵資訊，方便快速瀏覽
仔細校對
即使有AI語法檢查，也要手動校對。錯誤會損害信譽。
- 檢查拼寫錯誤及不自然的措辭
- 核實標點符號和拼寫
- 審核主旨欄準確性
常見陷阱與重要考量
避免過度自動化
不要完全依賴AI。過度使用AI會令電郵聽起來機械或缺乏人情味。
核實AI生成內容
AI可能出錯或「幻覺」事實。切勿盲目相信AI草稿。
- 務必核實日期、數字及具體說法
- 與可靠來源交叉核對事實資訊
- 確認姓名、職稱及公司資料
私隱及安全考量
謹慎輸入資料至AI工具。有些服務會記錄輸入內容，存在安全風險。
保持語氣敏感度
AI可能無法完全理解文化細微差異或幽默。撰寫跨文化電郵或涉及敏感話題時，需格外謹慎。
- 有疑慮時，傾向正式和富同理心的語氣
- 考慮文化溝通差異
- 仔細審核敏感話題的語氣
與人類技能平衡
記住同理心和創意來自你，而非AI。利用AI提升寫作，而非取代判斷。
一封精心撰寫的電郵仍需你的洞察力、情商和決策能力。AI是放大你能力的工具，而非替代品。
結論
利用AI草擬專業電郵對忙碌的專業人士來說可謂改變遊戲規則。明智使用時，它能提升生產力，同時不犧牲你的真實聲音或溝通質素。
始終配合良好電郵禮儀——校對錯誤、尊重收件人時間及保持禮貌語氣。平衡自動化與人類洞察力、同理心和創意。憑藉這些技巧，AI成為撰寫專業溝通、留下深刻印象的強大助手。
